Let's divide 41390 by 42
We're looking to find how many times 42 goes into 41390.

Step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 42

On to step 2:
41 divided by 42 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 42

Going ahead to step 3:
If we divide 413 by 42, we get 9 and a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 35 after subtracting 378 from 413.
Bring next digit (9) of the dividend behind the 35 and repeat the process: 359 / 42

On to step 4:
359 divided by 42 is 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Deduct 336 from 359 and we're left with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 42

Step 5:
The number 42 fits into 230 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 985.0
If we take 210 away from 230, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 6:
When dividing 200 by 42, we get 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 985.4
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
42 can be fit into 320 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 985.47
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
42 goes into 260 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 985.476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 985.4761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
When dividing 380 by 42, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 985.47619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 985.47619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
200 divided by 42 is 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 985.4761904
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
When dividing 320 by 42, we get 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 985.47619047
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 985.47619047 and a remainder of 2.6e-08.
